Have you paid attention to what kind of inkpad is used to write Buddhist scriptures or seal scripts related to Buddhism?

The material of inkpad is roughly the same, nothing special, and it will not do anything alone because it is related to Buddhism. In ancient times, the main ingredient was wormwood, which is very fine wormwood powder, but in modern times, there will be other plant raw materials to replace it. In ancient times, the color was cinnabar. In modern times, some chemical pigments are mixed, but the ancient method is still the main method. In ancient times, non-edible oils, such as castor oil, were mostly used for blending oil. Other vegetable oils have peculiar smell and need to be filtered and processed many times. Animal oil is perishable and cannot be used. Finally, special spices and other herbs are usually added to make the color of inkpad mixed with oil and grass paste more stable.
